A Scrying pool can be built as the centrepiece of the Portal Chamber in a player-owned house. It requires 80 Construction and four marble blocks, and earns the player 2000 experience. It is the last centrepiece able to be built in the Portal Chamber, the first being the Teleport focus and the second being the Greater teleport focus. Like the teleport focus, it can still be used to direct portals to teleportation locations.
The scrying pool can be used to see the areas where players' portals would take them. This can be useful for using portals that take the player to dangerous locations (such as the wilderness) as the pool can be used to scout out the area before the portal is used.

When creating your teleports, location 1 is the portal to the left of the door when walking into the portal chamber. Location 2 is directly opposite of the door. Location 3 is the portal to the right of the door when walking into the portal chamber.
